Due to changes in fashion and lifestyles extensions and internal alterations are increasingly popular when choosing an open-plan living area and designs are now driven by natural light and flow.

A rear extension will grant you more living space, better function and even overcome existing structural issues (as with Castle Way).


Jenner Construction have completed numerous rear extensions and each has been unique in its use. The Paddocks was a small utility room that was desired to suit the customers hobbies and lifestyle. The Castle Way rear extension was to overcome subsidence issues and failing external brickwork, the steel used was the biggest we have ever installed and was 7.4m long and produced a fantastic open space with level access to a patio and is flooded with natural light from 5m bi-fold doors and a 3.6m lantern complete with smart LED lighting to set the relaxing evening mood or liven up a party.
